Um, I've checked again, and I _don't_ find digits allowed in first
place in my patterns. . . I've now checked both my actual code, and
the message I sent that started this sub-thread, and the 0-9... only
appears in the second [...] group, that is, the Name pattern
is [...][...]+, and the 0-9 is (correctly, as you point out) not
present in the first [...].  Or did you find some other range there which
subsumes this?
